The fun, nimble 27.5-inch wheel platform plus the smooth, powerful Yamaha Pedelec motor equals huge fun. The Yamaha motor system perfectly marries smooth function with fun, unbridled power. It uses three sensors (torque sensor, speed sensor, and crank sensor) to create a wholly organic feeling of assist. It’s so smooth, you might forget that you’re pedaling uphill. The Li-Ion 400Wh battery is compact, tidy, and charges easily on or off the bike. It also easily locks onto the frame for added peace of mind when you’ve got to step away.

Yamaha's mid-drive motor system's overall theme is "smooth and powerful". It uses a torque sensor that detects pedaling power, a speed sensor that detects the bicycle's speed, and a crank sensor that detects the number of rotations through pedaling to create an organic feeling of assist. 

Features:

-Lightweight, compact 400Wh battery that can be charged on the bike, and be locked to the frame

-Zero Cadence Support ensures the system will engage at the first pedal stroke with lively, powerful assist

-Four power modes (OFF, ECO, STD, HIGH) let you choose the level of assist that you're feeling at the moment

-Navigate through a ton of metrics on the bright, easy to read display with the handy control unit
